LONDON (Reuters) - The World Health Organization (WHO) said on Thursday it remained worried about the spread of MERS, a respiratory disease that has infected and killed hundreds of people, overwhelmingly in Saudi Arabia.

In an update issued after a meeting of its emergency committee on Middle East Respiratory Syndrome, the United Nations health agency said more must be done to track the virus, which is known to have infected at least 965 people, of whom some 357 have died.
